The Good Addappt syncs contact information automatically to everyone in your network. It's great for sending group communications, making it perfect for business.
The Bad The app is only useful if you can get your contacts to use it, too.
The Bottom Line Despite a learning curve, Addappt is a powerful and business-friendly replacement for the iOS contact list.
Useful tools for group communications, if you can get your friends on board
Apple's default app does an adequate job of managing your contacts, but adequate isn't always good enough. By adding automatic updates to contact information behind the scenes, Addappt goes a needed few steps farther. With the latest version of the app, it's much easier to use and makes having the latest contact info a snap. That is, if you can get everyone you know to use it.
Fortunately, since it's a free download, you don't have to get your contacts to pay for the privilege. But there are better reasons to use it. As it tracks when others change their information, you get real time updates that don't require you to do a thing. That makes it especially useful and convenient for businesses, but note that it takes some patience to figure out how the app works.
Your home screen is basically a list with buttons to look at your personal contact info, connection requests from other people, a list of users that are already connected, and a group manager.
